Just a shout-out to Kiwix, the software plus database for reading Wikipedia offline. It’s incredibly helpful to have on your cell phone when you’re traveling and don’t have a data plan. Also nice just to have lightning-fast browsing of Wikipedia. They now have clients for iOS, Android, Windows, MacOS, and Linux.
You have to download the data separately. Their ZIM format seems well thought out, compressed tight and general purpose enough you can get other document collections like Stack Overflow posts, TED talks, etc. English Wikipedia is an enormous 35Gb, 80Gb if you get images too. There are various Wikipedia subsets but no “top articles” opton I see. (Be careful not to download a Simple English version by accident.)
The most interesting thing to me is Kiwix is now partnered with Wikimedia Foundation. A nice cash infusion, but also gives Kiwix some legitimacy. I’m hoping that gives a second wind to the editorial project to produce a Wikipedia subset that’s smaller and well selected to be sufficient.
There are some other offline Wikipedia readers on the Apple app store. I used Wiki Offline for years but the company that produced that seems to have disappeared (again). There’s also Minipedia which does have a nice small subset you can download. I think all of these alternatives found it hard to produce regular updates with the most recent Wikipedia content. Kiwix seems to be doing quarterly releases.
